Capacity and delay of two-way, two-lane STOP-sign intersections
The main purpose of this study was to investigate the impact of platoons of vehicles on the capacity and delay of unsignalized STOP-sign intersections and to improve the estimating techniques of capacity and delay for platoon situations. The study is based on the assumption that, at such a STOP-sign intersection, certain movements are given priority over others and that major street vehicles do not necessarily arrive at random but they arrive in platoons. NETSIM (Network Traffic Simulation Model) was used to simulate traffic operations at a two-way, two-lane STOP-sign intersection and to generate some traffic flow data for further analysis. Multiple Regression Analysis was done using the Statistical Packages for Social Sciences computer program to develop the two-model equations for capacity and delay. Equations developed indicated that the capacity and delay at an unsignalized STOP-sign intersection are not only affected by major street traffic volume, major street traffic speed, turning movements, etc., but also by the percentage of time vehicles are in platoons. Statistical tests done on the model delay equation and the observed data obtained from the field showed on significant difference the sets of data.
